Re: Ads for ESSCO RTTY/TU Products
I looked through my binder of 1967 73 Magazines, and found an ad on page
129.
It must have been the one that caught my eye since I see some scribbling on
that page with some prices, and a likely total that I'd pay for the
package.
I won't say that there were no other ads in the other 1967 73 Magazines,
since
I was doing my 'looking' in dim light. If anyone really wants to know
more, I
will look in the 1968 binder and see what is there. I would not know how
to
place such a scan onto an internet page, but if anyone else can do it I
can do
the scan and e-mail it to them for placement.

Just got another QRZ private message from WB1ASL. Turns out that he
does NOT have a M20. _It is a M26 that he has_.
I was willing to drive 10 hours (round trip) to get a M20, but not for
a M26 (already done that) or the rest of his collection.
So I am no longer interested in any of his machines. If any of you are,
looks like it is best to contact him via QRZ private message.
At least no one drove 3-5 hours to find out that it was a M26 and not a
M20!!
Have fun,
Duncan

Whoa! Does that name bring back some memories!
I had the complete ESSCO unit. All kits, some of which were based on the
"Transistorized
W2JAV TU" in the RTTY Handbook. ESSCO expanded and had everything else
needed, over and
above what the Handbook diagrams showed.
I used that package and made a bunch of contacts on 80M AFSK RTTY. I was
using wide
shift, with the high tones. The transmitter was a Drake T4X, that I had
modified with
the larger 'sweep tubes' that would fit the sockets and had the same
pin-out. I had to
leave the RF Cage off, though, since the replacement tubes were almost
3/4" taller. I
also had a 4" muffin fan on top of the transmitter at that corner of the
cabinet where
the tubes were. The 'sweep tubes' were capable of working outside of
their design
parameters, but they could be 'melted' if you were not careful. I took no
chances.
I also had to 'max out' the bias setting because with the bigger tubes,
the idle current
was up close to the 'max' that the Drake power supply could put out!
Seeing the plate
current almost 'hit the peg' made me reach for the power switch real
quick! I turned the
bias setting up to about 'half' of the swing of the control and tried
again. Still too
much idle current. I made one more attempt before setting the control to
'max'.
I've long since forgotten the entire list of cards, but there was one with
the TU circuitry,
an AFSK card, a 'Keyer card' with a transistor on a heat sink, a power
supply card, and
that's all I can remember.
Virtually everyone told me the same thing: "You have a good signal, but
your Space Tone
is quite weak compared to the Mark tone". Well, the Drake transmitter was
not designed to
pass audio much above 2200 Hz, so that is not surprising. I still made a
lot of contacts.
One day, I was home alone and tuning around on 20M I saw a signal, and
could recognize
the "CQ" so I tuned it in and it was from Australia! Solid copy! I got
the transmitter
all set and called him. Bingo! He came right back. I was so thrilled,
and had no one to
share this with. I saw a couple of neighborhood kids in the empty lot
next door and
hollered out the window for them to come to the house. I showed them the
Model 19 printing
something from the VK station, and told them what it was. They were
absolutely un-impressed!
They wandered off and I finished the QSO with him, sort of in a funk,
because the fact that
I was communicating with Australia meant nothing to these two (8-9 year
old?) girls.
- - - -
I later discovered that ESSCO made a narrow shift TU board and AFSK unit,
but I was on a
limited budget and didn't want to press my luck with the XYL, asking for
another $50 or so
to have narrow shift available.
There was a year when there was a Michigan Week Certificate issued by the
State of Michigan
to ham operators who made 10 or 15 QSOs with stations outside of Michigan,
promoting Michigan.
I made it a point that year to get my entire list of QSOs on RTTY. I had
to beg for the QSL
cards from a few guys who were sort of 'ho-hum' on certificates. I did
eventually get them all
and made my application. I got the certificate a few months later, and
was quite proud of it.
It made no mention of Mode of Operation, so it was just something that I
knew and was proud of.
Other than the odd shape of the ESSCO cabinet, I don't remember much more.
I don't remember if
I sold the TU package or swapped it or what.
Thanks for 'listening'.

Excellent Ralph! what was the date or aprox date you got the
unit!?
does anyone have any ads or catalogs!?
